The two are based on a new common PCB design that's shorter (10.4"), and uses a cost-effective component layout. The cooler also keeps up, it is more compact, and has a simpler heat pipe-based design. Both cards stick to the AMD reference clock speeds: 725/1000 MHz (core/memory) for the HD 5850, and 800/1000 MHz (core/memory) for the HD 5830. As far as connectivity goes, the HD 5830 V2 lacks one DVI.
